The comet shard of Anistar city

In Anistar city
a man in a small house his wife has recently left him to traveling who knows where
he asks you to bring him a pokemon so he does no longer feel as lonely
so you do
and about a week later he is gone
leaving a note and a pokeball with your pokemon inside
the note would have read that
he had died happily
he had left you a comet shard , a gift for the company
